Answer:
(a) x - y + 1 = 0
Step-by-step explanation:
One way to address multiple-choice questions is to try the answers to see what works.
For the lower left point (1, 2), the answer choices shown give ...
x -y +1 = 1 -2 +1 = 0 . . . . . equation works
-x -y +1 = -1 -2 +1 = -2 . . . doesn't work
y -x +1 = 2 -1 +1 = 2 . . . . . doesn't work
The appropriate choice is ...
x - y + 1 = 0
Lets find out how many pages he can read in a minute:
313.5 pages in (60*5)+30 = x minutes, x = 330 minutes
313.5/330 = .95 pages a minute
1 hour is 60 minutes
.95 * 60 = 57 pages in an hour.
Edit:
cross multiply to find how many pages read in an hour
313.5 pages x pages
-------- = -----------------
5 hours 30 mins (330 mins) 60 mins
(313.5*60)/330 = 57

Answer:
130 mg
Step-by-step explanation:
As the statement indicates that the daily recommended amount of calcium is 1,000 mg and that Velveeta contains 13% of that, you have to calculate the 13% of 1,000 to find the answer:
1,000*13%=130
According to this, there are 130 mg of calcium in one serving of Velveeta.
